I got the stack in ram works. it when execute the
dump_mem(dst, dst+0x100); print_debug("Jumping to LinuxBIOS.\r\n");
__asm__ volatile ( "cli\n\t" "leal _iseg, %edi\n\t" "jmp %edi\n\t" );
in copy_and_run.c, the jmp will cause cpu_reset.... It's strang....
I want to check in the cache_as_ram code, and it can coexist with old romcc code, ( by USE_DCACHE_RAM to switch..) Please let me know if you want to check that code in......
